The crushed coal gangue particles are widely used in solid backfilling. However, the nonuniform compaction and internal re-crushing behavior of crushed coal gangue under bearing stress have not yet been revealed in current research. But this is particularly significant for improving the filling effect and quality. In this article, with the …
This paper describes the experimental measurement of coal-mill transfer functions at a 380 Mw steam turbine generator of TransAlta Utilities in Canada. Measurement equipment was used that estimated the parameters of the transfer functions from digitized transients obtained during on-site tests. These preliminary tests were part of a sequence of tests …
People have always tended to regard the crushing and screening section of a flowsheet involving grinding mills simply as a function of feed preparation for those mills. Consequently, in most operations, crushing plant opera- tors produce mill feed as fast as possible. But the fastest feed rate produces the coarsest material, causing any sub-
Raw sugar is produced from juice in sugar cane crushed by a series of mills. To improve the extraction a liquid bath is applied to the cane between mills. This liquid bath, commonly called maceration, consists of water and some of the produced juice. Although the extraction is improved with higher water content in the maceration, the total …
